Benzimidazolones: A new class of selective peroxisome proliferator- activated receptor gamma (PPARgamma) modulators

A series of benzimidazolone carboxylic acids and oxazolidinediones were designed and synthesized in search of selective PPARgamma modulators (SPPARgammaMs) as potential therapeutic agents for the treatment of type II diabetes mellitus (T2DM) with improved safety profiles relative to rosiglitazone and pioglitazone, the currently marketed PPARgamma full agonist drugs. Structure-activity relationships of these potent and highly selective SPPARgammaMs were studied with a focus on their unique profiles as partial agonists or modulators. A variety of methods, such as X-ray crystallographic analysis, PPARgamma transactivation coactivator profiling, gene expression profiling, and mutagenesis studies, were employed to reveal the differential interactions of these new analogues with PPARgamma receptor in comparison to full agonists. In rodent models of T2DM, benzimidazolone analogues such as (5R)-5-(3-{[3-(5-methoxybenzisoxazol-3-yl)benzimidazol-1-yl]methyl}phenyl) -5-methylox-azolidinedione (51) demonstrated efficacy equivalent to that of rosiglitazone. Side effects, such as fluid retention and heart weight gain associated with PPARgamma full agonists, were diminished with 51 in comparison to rosiglitazone based on studies in two independent animal models.

Synthesis and Biological Evaluation of 1-(1,2-Benzisothiazol-3-yl)- and (1,2-Benzisoxazol-3-yl)piperazine Derivatives as Potential Antipsychotic Agents

Members of the series of title compounds were tested for potential antipsychotic activity in relevant receptor binding assays and behavioral screens.Structure-activity relationships within the series are discussed.Compound 24 (BMY 13859-1), a (1,2-benzisothiazol-3-yl)piperazine derivative, was selected for further study because of its potent and selective profile in primary CNS tests.It was active in the Sidman avoidance paradigm and blocked amphetamine-induced stereotyped behavior in dogs for up to 7 h.The compound’s lack of typical neuroleptic-like effects in therat catalepsy test and its failure to produce dopamine receptor supersensitivity following chronic administration indicate that it should not cause the movement disorders commonly associated with antipsychotic therapy.Although 24 has potent affinity for dopaminergic binding sites, its even greater affinity for serotonin receptors suggests that a serotonergic component may be relevant to its atypical profile.Compound 24 is currently undergoing clinical evaluation in schizophrenic patients.

Validating and enabling phosphoglycerate dehydrogenase (PHGDH) as a target for fragment-based drug discovery in PHGDH-amplified breast cancer

3-Phosphoglycerate dehydrogenase (PHGDH) has recently been identified as an attractive target in cancer therapy as it links upregulated glycolytic flux to increased biomass production in cancer cells. PHGDH catalyses the first step in the serine synthesis pathway and thus diverts glycolytic flux into serine synthesis. We have used siRNA-mediated suppression of PHGDH expression to show that PHGDH is a potential therapeutic target in PHGDH-amplified breast cancer. Knockdown caused reduced proliferation in the PHGDH-amplified cell line MDA-MB-468, whereas breast cancer cells with low PHGDH expression or with elevated PHGDH expression in the absence of genomic amplification were not affected. As a first step towards design of a chemical probe for PHGDH, we report a fragment-based drug discovery approach for the identification of PHGDH inhibitors. We designed a truncated PHGDH construct that gave crystals which diffracted to high resolution, and could be used for fragment soaking. 15 fragments stabilising PHGDH were identified using a thermal shift assay and validated by X-ray crystallography and ITC competition experiments to exhibit 1.5-26.2 mM affinity for PHGDH. A structure-guided fragment growing approach was applied to the PHGDH binders from the initial screen, yielding greater understanding of the binding site and suggesting routes to achieve higher affinity NAD-competitive inhibitors.

Hypoxia-Selective Antitumor Agents. 3. Relationships between Structure and Cytotoxicity against Cultured Tumor Cells for Substituted N,N-Bis(2-chloroethyl)anilines

A series of aniline mustards with a wide range of electron-donating and -withdrawing substituents in the 3- and 4-positions has been synthesized and evaluated for cytotoxicity in cell culture to examine the potential of using nitro group deactivated nitrogen mustards for the design of novel hypoxia-selective anticancer drugs (Denny, W.A.; Wilson, W.R.J.Med Chem. 1986, 29, 879).Hydrolytic half-lives in tissue culture media, determined by bioassay against a cell line (UV4) defective in the repair of DNA interstrand cross-links showed the expected dependence on the Hammett electronic parameter, ?, varying from 0.13 h for the 4-amino analogue to >100 h for analogues with strongly electron-withdrawing substituents.Cytotoxic potencies in aerobic UV4 cultures showed a similar dependence on ?.This dependence predicted that the 4-nitroaniline mustard would be 7200-fold less potent than its potential six-electron reduction product, the 4-amino compound, in growth inhibition assays using a 1-h drug exposure.The measured differential was much lower (225-fold) because of the instability of the latter compound, but a differential of 17500-fold was observed in the initial rate of killing by using a clonogenic assay.The potential for formation of reactive mustards by reduction to the amine or hydroxylamine was demonstrated by the 4-nitroso compound, which had an aerobic toxicity similar to that of the amine.Although these features confirmed the original rationale, the 3-nitro- and 4-nitroaniline mustards had only minimal hypoxic selectivity against UV cells.Toxicity to hypoxic cells appears to be limited by the low reduction potentials of these compounds and consequent lack of enzymatic nitroreduction.However, this study has demonstrated that nitro groups can be used to latentiate aromatic nitrogen mustards and indicates that examples with higher reduction potentials could provide useful hypoxia-selective therapeutic agents.
